Mass, Sarah J. Throne of Glass.

“What if Cinderella was an assassin and went to the ball not to dance with the prince, but to kill him?” That was the author’s inspiration for Throne of Glass. Enter a medieval world with a brutal king who rules with an iron fist. In need of a royal enforcer to keep his subjects in line, he finds Celaena Sardothien, the Assassin of Adarlan, languishing in his salt mine prison. She’s a fierce warrior, but can she outfight 23 men in the king’s brutal competition to become the king’s enforcer? And, at what price?
